Bout agreements have been distributed, and at least one of the fighters has already put pen to paper.

Featuring a featherweight title fight between current champ Jose Aldo and an ever-popular challenger in Urijah Faber, WEC 48 takes place April 24 at the ARCO Arena in Sacramento, Calif. The event marks the organization’s first foray into the pay-per-view market.

Karalexis fights for the first time since March 2009. The Massachusetts had been scheduled to fight Kamal Shalorus at this past November’s WEC 44 event, but a broken hand forced him out of the matchup.

A three-time UFC veteran and cast member of the original season of “The Ultimate Fighter,” Karalexis has earned WEC wins over Greg McIntyre, Josh Smith, Olaf Alfonso and Thomas Denny. He has also suffered a pair of losses in contests with Bart Palaszewski and Ed Ratcliff.

Meanwhile, Micklewright looks to build on the success of a unanimous-decision win over former EliteXC vet Muhsin Corbbrey at this past December’s WEC 45 event. The result was just the second decision of Micklewright’s budding career.

Prior to his current stint in the WEC, Micklewright was the lightweight champion of the Iowa-based Glory Fighting Championships organization.
